In a nutshell: This free iPhone 5S app makes it a breeze to track your steps and become more physically active.

Cool factor: Breeze helps you get fit, without needing a separate device like a Fitbit. Unlike other pedometer apps, you don't have to remember to press "start," because Breeze works automatically. First, it grabs one week's activity data from the phone's M7 chip, a special motion-detection, battery saving processor. Then it tracks steps in real time, displays your progress toward daily goals and sends texts of encouragement. You might be surprised how that knowledge can prod you to walk a little farther to reach the goals.

Note: Only available for the iPhone 5S. FitnessKeeper, which makes other apps like RunKeeper, isn't saying when or if Breeze might come to other mobile devices.
